One Day a fleet of alien spaceships suddenly descend from the sky. After getting over the initial shock, the aliens broadcast to every device on the planet, there peaceful intentions and proposal: The planet had been randomly selected to host an exciting and sexy martial arts tournament known as The Gerrabacco Tournament.

The Gerrabacco Tournament is a Free-For-All Battle Royale Tournament, in which everyone on the planet may participate. Individuals or entire species and races may form teams to increase the overall odds of their victory. To win the tournament, one individual must collect the five C̶h̶a̶o̶s̶ ̶E̶m̶e̶r̶a̶l̶d̶s̶ Emeralds of Power, scattered across the islands. Whomever collects all 5 Emeralds first will be granted Phenomenal Cosmic Power and 10 Billion Zenni.

If someone collects the individual Emeralds before someone else, the Emeralds can be stolen from them by either defeating them in combat or draining their stamina sexually.

Bear in mind, the Alien Ships contain particpants and possible veterans from across the galaxy who are also after a chance to win, and most of the native species and organizations will likely organize into makeshift armies to win and share the prizes as well.

Individuals not participating in the tournament can just go about their day-to-day lives and watch the planet wide battle-orgy about to unfold.
